[0016]
A portion 31 (FIGS. 9 and 11) where the rotating shaft 19 is provided below the left and right surrounding portions 21 of the back portion 17 is formed in a plate-like convex arc shape. The arc-shaped portion 31 is formed around the rotation shaft 19. Corresponding to the convex arc-shaped portion 31, concave arc-shaped portions 33 are formed on the left and right sides of the seat portion 11 (FIG. 11), and the convex arc-shaped portion 31 is received. It has become.
[0017]
(Interlocking mechanism 45)
The convex arc-shaped portions 31 exist on the left and right sides, and the inner surfaces facing each other are exposed from the seat (see FIG. 8). A protruding portion 35 (FIG. 11) is formed in the exposed portion, and a rotation hole 37 is formed in the protruding portion 35. One end side of the interlocking bar 39 is rotatably attached to the rotation hole 37.
[0018]
That is, the interlocking bar 39 as a whole has a U-shape, both ends of the U-shape are bent in an L-shape, and are fitted in the rotation hole 37 so as to be freely rotatable. A depression 41 is formed in the concave arc-shaped portion 33 within a range in which the projection 35 rotates. Both ends of the recess 41 are stoppers that abut against the protrusion 35 and restrict the rotation of the seat portion 11.

[0020]
Thus, the interlocking mechanism 45 having the interlocking bar 39 is configured. When the back portion 17 is rotated with respect to the seat portion 11 by the operation of the interlocking mechanism 45, the interlocking bar 39 attached to the back portion 17 pushes the back surface of Step 23, and Step 23 has a predetermined rotation angle.
[0021]
(Tilt lock mechanism 53)
The inclined state of the back portion 17 is supported by the support bar 47 (FIGS. 5, 8, 9, and 10). The entire support bar 47 has a U-shape (FIG. 8). Both ends of the U-shape are bent into an L shape, and the bent portion is formed in the hole 49 (FIG. 5) of the seat portion 11. It is fitted so that it can be rotated, and the fitted tip is stopped by a push nut to prevent it from coming off. This push nut is fitted into a recess formed around the hole 49. The central side of the U-shape engages with an engagement recess 51 provided in multiple stages on the back surface of the back portion 17 (FIG. 10).
[0022]
By automatically performing this engagement, a tilting lock mechanism 53 that locks the tilting movement, that is, tilting of the back portion 17 is provided.

That is, as shown in FIG. 10, a rotation cover 55 that covers the engagement recesses 51 provided in multiple stages is attached to the back surface of the back portion 17 so as to be rotatable around a rotation shaft 57. The rotating cover 55 has a box shape with the left surface in FIG. 10 opened, and can take a state of surrounding and covering the engaging recess 51 and a state of separating from the engaging recess 51 by rotation. . This rotation is performed by placing a finger on the handle portion 58 (FIGS. 8 and 10) provided on the upper portion of the rotation cover 55. Long holes 59 are formed on the left and right side surfaces of the rotary cover 55 in the vertical direction. The central side of the U-shape of the support bar 47 passes through the left and right elongated holes 59 and is held slidably.
[0024]
In the state in which the rotation cover 55 covers the engagement recess 51, the support bar 47 is fitted into the engagement recess 51, and in the state of being separated, the support bar 47 is detached from the engagement recess 51. It becomes possible to slide.

The other end of the connecting member 73 is rotatably attached to the shaft 74 (FIG. 8) of the headrest 27. Therefore, when the rotation angle of the back portion 17 becomes large and becomes a sleeping state, the support bar 47 moves to above the long hole 59 and pushes the connecting member 73. The pushed connecting member 73 rotates the headrest 27 counterclockwise in the drawing. As a result, the headrest 27 stands and can support the sleeping infant's head so as not to jump out (FIGS. 7 and 9). The connecting member 73 is urged downward along the long hole 59 by the spring 75 and returns to its original state when it is not pushed by the support bar 47.
[0028]
The tilt lock mechanism 53 and the headrest coupling mechanism 69 are described in detail in application publications (actual fair 7-27887, actual fair 7-27888) already filed by the applicant.

Further, downward grooves 77 (FIGS. 2, 3, 5, 8, 9, and 11) for receiving the two swing bars 7 are formed on the bottom surface of the seat portion 11, respectively. The received swing bar 7 is held in the groove by a clip (not shown).
[0030]
(Leg 3)
As shown in FIGS. 17 and 18, the leg portion 3 includes an upper script pair 111 and two lower leg members 113. Each leg 113 is provided with a wheel 115 at the lower end. The front wheel 115 is provided via a caster 117 so that the traveling direction can be easily changed.
[0031]
The rear leg 113 is hinged to the leg body 111. The other leg member 113 is hinge-coupled to the hinge coupling portion 121 of the slide bar 119. A slide bar 119 provided integrally with the hinge coupling portion 121 is housed in the leg body 111 so as to be slidable in the front-rear direction.
[0032]
That is, the long hole 123 is formed in the slide bar 119 in the front-rear direction, that is, the longitudinal direction. The long hole 123 is also formed continuously in the hinge coupling part 121. Two pins 125 provided in the leg main body 111 and arranged at a predetermined interval pass through the long hole 123. The slide bar 119 is urged by a spring (not shown) in the left direction in FIG. 18, that is, in the direction in which the leg portion 3 extends and becomes higher.
[0033]
The slide bar 119 has a square cross section. On the upper surface of the slide bar 119, a plurality of adjustment holes 127 are formed side by side in the longitudinal direction. Pins 129 to be inserted into these adjustment holes 127 are provided on the leg main body side so as to be movable up and down. That is, the pin 129 is urged in the insertion direction, that is, downward by the spring 131. In addition, a lever 135 is provided in the middle of the pin 129 so as to be engaged with a portion 133 whose diameter has been enlarged. Is done. The lever 135 is provided to be movable up and down in the longitudinal direction of the pin 129.
[0034]
With these configurations, when the lever 135 is pulled upward from the outside of the leg main body 111, the pin 129 moves upward against the biasing force of the spring 131 and is removed from the adjustment hole 127. When the pin 129 is disengaged, the slide bar 119 moves to the left in the figure by the action of a spring (not shown), thereby extending the leg 3 that is hinged and intersecting in an X shape to increase its height.
[0035]
If the lever 135 is released while the slide bar 119 slides, the pin 129 is inserted into the adjustment hole 127 again by the biasing force of the spring 131, and the leg portion 3 maintains a predetermined height. Five adjustment holes 127 are opened, so that the height is adjusted to five levels when the infant seating apparatus 1 is used. The fifth-stage adjustment hole 127 (the adjustment hole into which the pin 129 is inserted in the drawing) is a longer hole than the other adjustment holes 127, and also serves as the adjustment hole 127 in the housed state described later. Yes.
[0036]
(Stopper 141)
A stopper 141 that comes into contact with the leg material 113 is provided on the bottom surface of the leg main body 111. That is, the X-shaped shape of the leg 3 is advantageous in terms of strength, but if the crossing angle of X becomes too small, for example, when it becomes 0, the advantage in strength is lost. For this reason, the stopper 141 abuts on the upper side of the one leg member 113, and the leg member 113 is not folded any further, so that a desirable minimum required crossing angle can be secured.
[0037]
In the present embodiment, the stopper 141 is configured to be rotatable around a rotation shaft 143 as shown in FIG. Further, the stopper 141 is urged by a spring 145 in the clockwise direction in the drawing, that is, in a direction to be positioned between the leg main body 111 and the leg member 113. A recess 147 is provided below the stopper 141, and a finger is hooked on the recess 147 to rotate counterclockwise, so that it can be separated from the leg member 113.
[0038]
Therefore, in a normal use state, the stopper 141 is positioned between the leg main body 111 and the leg member 113 by the action of the spring 145, and thus contacts the leg member 113. This prevents the X crossing angle from becoming smaller than the required minimum crossing angle. In this manner, the height adjustment from the first stage to the fifth stage is performed as described above.
[0039]
When the infant seating apparatus 1 is stored, the finger is hooked on the stopper 141 and rotated counterclockwise in the figure, and thus moved outward and separated from the leg material 113. As a result, the legs can be moved upward, folded deeply, and the height of the legs can be lowered. As a result, the storage space can be further reduced. At this time, the crossing angle of X becomes very small or becomes zero, but there is no inconvenience because a large force is not applied to the legs when the infant seating apparatus is not used.
[0040]
At this time, it is possible to make the entire infant seating device even flatter and more compact by laying the back part sufficiently against the seating surface so that the seat part, the back part, and the entire step are almost horizontal. is there.
